Generate JBang config from //Q:CONFIG

[radcortez]

Description

We must propagate the JBang config set by //Q:CONFIG. To achieve this, we added a setRuntimeProperties in the QuarkusBootstrap builder. Currently, only JBang uses this API, but it is widely available for other pieces (build, tests, etc.).

While adding a setRuntimeProperties was an easy fix, it may cause issues if someone uses it outside its intended behavior (record runtime properties during build).

See:

• Add runtime properties to Quarkus builder #43160
• Propagate Runtime properties in JBang Dev mode #44415

Implementation ideas

We could eliminate the API by generating config sources for //Q:CONFIG instead and attaching them to the project.
